WILLIAM W. MCCHESNEY, OF ASBURY PARK, NEW JERSEY, ASSIGNOR OF ONE-HALF TO JAMES H. MACKINTOSI-I, OF SAME PLACE.

PIPE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 614,255, dated November 15, 1898.

I Application led January 27, 1898. Serial No. 668,202. (No model.)

To all whom t may concern:

Be it known that I, WILLIAM W. MoCHEs- NEY, a citizen of the United States, residing at Asbury Park, in 'the county of Monmouth and State of New Jersey, have invented certain new and useful Improvements in a CombinedPipe-Tongs, Monkey-Wrench,and Gant- Hook; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a combined pipetongs, monkey-wrench, and cant-hook; and its primary object is to providea simple and effective tool designed to serve these purposes.

A further object is to provide a tool having one of its jaws formed witha curved toothed face and the other jaw with a series of straight faces arranged at an angle to each other, whereby a firm three-point bearing on the pipe or object to be held or moved is obtained and all liability of crushing the pipe obviated.

A still further object is to provide one of the jaws of the tool with a rear auxiliary or secondary toothed face adapted to form, in eonj unction with the main toothed face thereof, an angular recess for receiving,r large' pipe and increasing the capacity of the wrench, and also toV provide an extensible handle which may be adjusted to afford greater leverage.

I attain these objects. by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of -a tool constructed in accordance with my invention. Fig. 2 is a side elevational View of the fixed jaw of same. Fig. 3 is a perspective view showing a modification in which the fixed jawl is formed with the ,straight faces, and Fig. 4 is a side elevational view of the ,fixed jaw shown in Fig. 3.

Referring now more particularly to the said drawings, Alrepresents the handle of the tool,

which may be of any desired length or size, and B the curved fixed jaw at one end thereof, said jaw being provided on its inner face with teeth or serrations C, extending. in the arc of a circle. At the upper or rear end of this toothed face the jaw is formedwith inclined side shoulders d and with a curved toothed face E, extending rearwardly from said shoulders and forming with the said toothed face C an angular recess or depression e.

The swinging jaw F is bifureated at its inner end to form arms g, which project substantially at right anglesthereto, and these arms straddle the handle and are pivotally connected therewith by a pin or bolt h at a point just in rear of the shoulders d,'which limit the forward movement of said swinging jaw, and below the toothed face E. kThe inner face of this jaw is formed with three straight engaging faces-a central face t' and end or side faces j and la, which incline toward'the central face to form angles Z therewith-the face i extending at right angles to ythe bifurcated end of the jaw and all of said faces being toothed or serrated, as shown. When the swinging jaw is closed, as shown in full lines in Fig. l, the bifurcatedend thereof covers the toothed face E but when the jaw is swung to its fullest open position, as shown in dotted lines, this toothed face is uncovered and brought into operative position.

Vare .attainedV by the novel arrangement of the toothed faces, which afford a three-point bearing o n the circumference of the pipe to be grasped, whereby the pipe is not only held firmly and the pressure brought to bear equally from all three sides toward the center thereof, but liability of the pipe slipping or being crushed by unequal or improperly-directed pressure is entirely obviated. The capacity of a wrench of given size is also greatly increased by the addition of the toothed face E, which, in conjunction with the toothed face G of the fixed jaw and one of the faces of the swingingfjaw, serves to rmly retain in position the largest-sizedpipe IOO the wrench is adapted to hold. It will be understood that such pipes rest in the depression or recess e and that the three-point bearing is formed by the toothed faces C, E, and t'.

In employing the tool as a monkey-wrench the jaws thereof are applied on opposite sides of thenutin the usual mannerand operated by a bacliandfo1-th movement, like a ratchetwrench, or the tool is given a continuous rotary movement, according to space afforded, to apply the nut to a bolt or release it therefrom. The jaws readily adjust themselves to nuts of different sizes. The tool also provides an efficient cant-hook for general use for handling boards and iron-work,but is particularly useful in bridge, elevated-railroad, and fireproof-building construction where iron-work is employed, the peculiar construction of the jaws enabling angle irons and beams to be rigidly held andtransported. It is also useful in surface-railroad construction and in setting tires on vehicle-wheels. I do not, therefore, lilnit my invention to any particular manner of use, as it is capable of being employed for many useful purposes other than those specifically mentioned herein.

If desired, the handle A of the tool maybe made extensible by providing the same with a sliding sleeve M, having a set-screw n to hold it in position. By means of this sleeve the handle may be lengthened to afford increased purchase and leverage.

In the embodiment of my invention disclosed in Figs. 3 and 4 I provide the swinging jaw with the continuous curved toothed face G and the fixed jaw with the straight faces j k; but otherwise the construction is essentially the same.

From the above description, taken in connection with the accompanying drawings, the construction and mode of operation of my invention will be readily understood, and it will be seen that a simple and effective tool for the purpose stated is provided.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is-

1. A tool of the class described, consisting of a handle provided with a fixed jaw and a swinging jaw, one of said jaws being formed with a curved, toothed main face and the other jaw with a series of straight toothed main faces extending at an angle to each other, and the said fixed jaw having adjacent to the pivotal point of the swinging jaw a rear or auxiliary toothed face forming, in conjunction with its main face, an angular depression or recess, substantially as described.

2. A tool of the cla-ss described, consisting of a handle provided with a fixed jaw having a curved, toothed main face and a rear toothed face forming in conjunction therewith an angular depression or recess, and a swinging jaw bifurcated to form arms pivoted to the handle adjacent to said rear face and provided with a series of straight faces arranged at an angle to each other, substantially as described.

3. A tool of the class described, consisting of a handle provided with a fixed jaw having a curved, toothed main face and a reartoothed face forming in conjunction therewith an angular depression or recess, a swinging jaw bifurcated to form arms pivoted to the handle adjacent to said rear face and provided with a series of straight faces arranged at an angle to each other, and a sliding sleeve or extension on said handle, substantially as described.

In testimony whereof I afiix my signature in presence of two witnesses.

VILLIAM XV. MCCIIESNEY.
